Poor assistance with eSim

I would like to file a complaint regarding the poor service I received from the Vodacom store consultants at Midstream Chatz and the Vodacom contact center. I have been trying to get my eSim activated for the past three days. I visited the store on Monday morning to replace my SIM with an eSim, but since then, I have been sent from one person to another without any resolution. The issue has to do with not receiving the email containing the QR code. Instead of addressing the root cause of the email not being received on my end, everyone I speak to just keeps resending the same email which isn't solving the problem. I receive all other emails except the one with the QR code. As a result, I have been unable to make or receive calls for three days, and it's significantly impacting me.
